• ### Demagnetizing-field induced instability in the superferromagnetic (CoFe$_{2}$O$_{4}$)$_{20}$Ag$_{80}$ nanocomposite

Publication Year: 2017, Page(s): 1
| | PDF (22348 KB)

The magnetic properties of the (CoFe$_{2}$O$_{4}$)$_{20}$Ag$_{80}$ nanocomposite packed into a cylindrical sample-holder were investigated. The nanoparticles system was found to become superferromagnetic (SFM) below 223 K. The SFM state was investigated by measuring the temperatu... View full abstract»

• ### Quantum Dynamics as Landau-Lifshitz-Type Dynamics and Random Wave Function Collapse

Publication Year: 2017, Page(s): 1
| | PDF (329 KB)

It is first observed that quantum dynamics can be viewed as Landau-Lifshitz-type dynamics. Then, by using this fact, instability induced random branching of deterministic dynamics is discussed as a possible mechanism of random wave function collapse. In the case of two-level systems important in quantum computing and spintronics, the Born probability rule emerges as the simplest solution to the eq... View full abstract»

• ### Ferromagnetic $\rm {Gd}_{5}\rm {Si}_{4}$ nanoparticles as T2 contrast agents for MRI

Publication Year: 2017, Page(s): 1
| | PDF (1174 KB)

Room temperature ferromagnetic $\rm {Gd}_{5}\rm {Si}_{4}$ nanoparticles were synthesized using arc-melting and high energy ball milling. We have demonstrated that these particles can be used as potential T2 contrast agents for magnetic resonance imaging. The ball milled $\rm {Gd}_{5}\rm {Si}_{4}$ nanostructured material shows ferromagneti... View full abstract»

• ### Magneto-Electric (ME) Effect Modeled in a Non-Linear Experiment

Publication Year: 2017, Page(s): 1
| | PDF (910 KB)

This paper presents a non-linear model and experimental assessment of a Magneto-Electric (ME) device fabricated using a hexaferrite film and a spiral coil. In both model and experiment, two sources are applied to the ME film and the spiral coil. The ME effect is modeled by two equation based sources for generating the ME effect from the ME film to the spiral coil (and vice versa). A simple equival... View full abstract»

• ### Poly(Lactic Acid) Magnetic Microparticle Synthesis and Surface Functionalization

Publication Year: 2017, Page(s): 1
| | PDF (512 KB)

Iron oxide nanoparticles have been employed for a variety of biomedical applications in both the diagnostic and therapeutic realm and the number of applications continues to grow. In the work presented here, magnetic nanoparticles were synthesized via aqueous co-precipitation and subsequently coated in oleic acid to confer colloidal stability in organic solvents. The synthesized nanoparticles were... View full abstract»

• ### Ferroelastic strain mediated nonvolatile tuning of perpendicular magnetic anisotropy in (Co/Pt)$_{3}$/(111) Pb(Mg$_{1/3}$Nb$_{2/3}$)O$_{3}$-PbTiO$_{3}$ multiferroic heterostructures

Publication Year: 2017, Page(s): 1

Nonvolatile control of perpendicular magnetic anisotropy (PMA) is of great technological importance for low power spintronic devices. In this study, we successfully achieved ferroelastic strain mediated nonvolatile tuning of PMA at room temperature in (Co/Pt)$_{3}$/(111) Pb(Mg$_{1/3}$Nb$_{2/3}$)O View full abstract»

• ### Dependence of Predicted HAMR Areal Density on Common Optimization Strategies

Publication Year: 2017, Page(s): 1
| | PDF (538 KB)

The ultimate user area density of heat assisted magnetic recording is a very important issue for both industry and researchers. In this letter, we first propose two new algorithms to accelerate the recording simulation using general-purpose computing graphics processing units. Then we predict user area density with current technologies and those expected to be available in the near future. Microma... View full abstract»

• ### Normally-Off Computing and Checkpoint/Rollback for Fast, Low-Power and Reliable Devices

Publication Year: 2017, Page(s): 1
| | PDF (1028 KB)

Since the advent of complementary metal oxide semiconductors (CMOS), the number of transistor per die never stops increasing to reach today several billion of transistors. As a result, design and fabrication of smart devices able to run at high speed has been possible. However, the power consumption of systems-on-chip has significantly increased due to the high density integration and the high lea... View full abstract»

• ### Low Barrier Nanomagnets as p-bits for Spin Logic

Publication Year: 2017, Page(s): 1
| | PDF (4273 KB)

It has recently been shown that a suitably interconnected network of tunable telegraphic noise generators or \p-bits" can be used to perform even precise arithmetic functions like a 32-bit adder. In this paper we use simulations based on the stochastic Landau-Lifshitz-Gilbert (sLLG) equation to demonstrate that similar impressive functions can be performed using unstable nanomagnets with energy ba...

• ### Improvement of magnetic properties in microfabricated FePt and Fe nanocomposites upon post-annealing

Publication Year: 2016, Page(s): 1
| | PDF (1089 KB)

In order to evaluate the magnetic properties of cylindrical nanocomposite magnets, microfabrication, electron beam lithography, and Ar ion etching were used to prepare hard, ring-shaped, L10 ordered FePt structures embedded with bcc Fe cores. L10 FePt has high uniaxial magnetic anisotropy, moderate saturation magnetization, and excellent corrosion resistance. Magnetic properties were measured by m... View full abstract»
