Temperature-driven changes in the Fermi surface of graphite
Laxman R. Thoutam, Samuel E. Pate, Tingting Wang +7
We report on temperature-dependent size and anisotropy of the Fermi pockets in graphite revealed by magnetotransport measurements. The magnetoresistances obtained in fields along t…
First-principles study of magnetic states and the anomalous Hall conductivity of NbS (=Co, Fe, Mn, and Ni)
Hyowon Park, Olle Heinonen, Ivar Martin
Inspired by the observation of the extremely large anomalous Hall effect in the absence of applied magnetic fields or uniform magnetization in CoNbS [Nature Comm. 9, 3280 (…
Magnetization governed magnetoresistance anisotropy in topological semimetal CeBi
Yang-Yang Lyu, Fei Han, Zhi-Li Xiao +10
Magnetic topological semimetals, the latest member of topological quantum materials, are attracting extensive attention as they may lead to topologically-driven spintronics. Curren…
Orbital-flop Induced Magnetoresistance Anisotropy in Rare Earth Monopnictide CeSb
Jing Xu, Fengcheng Wu, Jin-Ke Bao +12
The charge and spin of the electrons in solids have been extensively exploited in electronic devices and in the development of spintronics. Another attribute of electrons - their o…
Weak crystallization theory of metallic alloys
Ivar Martin, Sarang Gopalakrishnan, Eugene A. Demler
We extend the Weak Crystallization theory to the case of metallic alloys. The additional ingredient -- itinerant electrons -- generates nontrivial dependence of free energy on the…
Localized ferromagnetic resonance force microscopy in permalloy-cobalt films
E. Nazaretski, Yu. Obukhov, I. Martin +5
We report Ferromagnetic Resonance Force Microscopy (FMRFM) experiments on a justaposed continuous films of permalloy and cobalt. Our studies demonstrate the capability of FMRFM to…
Observation of localized ferromagnetic resonance in a continuous ferromagnetic film via magnetic resonance force microscopy
E. Nazaretski, D. V. Pelekhov, I. Martin +5
We present Magnetic Resonance Force Microscopy (MRFM) measurements of Ferromagnetic Resonance (FMR) in a 50 nm thick permalloy film, tilted with respect to the direction of the ext…
Spatial characterization of the magnetic field profile of a probe tip used in magnetic resonance force microscopy
E. Nazaretski, E. A. Akhadov, I. Martin +3
We have developed the experimental approach to characterize spatial distribution of the magnetic field produced by cantilever tips used in magnetic resonance force microscopy (MRFM…
Ferromagnetic resonance force microscopy on a thin permalloy film
E. Nazaretski, D. V. Pelekhov, I. Martin +6
Ferromagnetic Resonance Force Microscopy (FMRFM) offers a means of performing local ferromagnetic resonance. We have studied the evolution of the FMRFM force spectra in a continuou…
Efficiency of thin film photocells
D. Mozyrsky, I. Martin
We propose a new concept for the design of high-efficiency photocells based on ultra-thin (submicron) semiconductor films of controlled thickness. Using a microscopic model of a th…
A scheme for electrical detection of spin resonance signal from a single electron trap
I. Martin, D. Mozyrsky, H. W. Jiang
We study a scheme for electrical detection of the spin resonance (ESR) of a single electron trapped near a Field Effect Transistor (FET) conduction channel. In this scheme, the res…
Magnetic-field dependence of electron spin relaxation in n-type semiconductors
Franz X. Bronold, Ivar Martin, Avadh Saxena +1
We present a theoretical investigation of the magnetic field dependence of the longitudinal () and transverse () spin relaxation times of conduction band electrons in n-t…
