Superconducting fluctuation in FeSe investigated by precise torque magnetometry
Hideyuki Takahashi, Fuyuki Nabeshima, Ryo Ogawa +3
We investigated the superconducting fluctuation in FeSe, which is assumed to be located in the BCS--BEC crossover region, via magnetic torque measurements. In our method, the absol…
Force-detected high-frequency electron spin resonance spectroscopy using magnet-mounted nanomembrane: robust detection of thermal magnetization modulation
Hideyuki Takahashi, Tsubasa Okamoto, Kento Ishimura +3
In this study, we report a conceptually novel broadband high-frequency electron spin resonance (HFESR) spectroscopic technique. In contrast to the ordinary force-detected ESR techn…
New method for torque magnetometry using a commercially available membrane-type surface-stress sensor
Hideyuki Takahashi, Kento Ishimura, Tsubasa Okamoto +2
We present a new method for torque magnetometry by using a commercially available membrane-type surface-stress sensor (MSS). This sensor has a silicon membrane supported by four be…
Wide-Dynamic-Range Cantilever Magnetometry Using a Fiber-Optic Interferometer and its Application to High-frequency Electron Spin Resonance Spectroscopy
Hideyuki Takahashi, Tsubasa Okamoto, Eiji Ohmichi +1
We present a method of broadening the dynamic range of optical interferometric detection of cantilever displacement. The key idea of this system is to use a wavelength-tunable lase…
Cantilever detected ferromagnetic resonance in thin FeNi, CoFeAlSi and SrFeMoO films using a double modulation technique
Alexey Alfonsov, Eiji Ohmichi, Pavel Leksin +5
In this work we introduce a new method of a ferromagnetic resonance (FMR) detection from thin, nm-size, films. Our setup is based on the commercial piezo-cantilever, used for atomi…
Anomalous Spin Dynamics observed by High Frequency ESR in Honeycomb Lattice Antiferromagnet InCu2/3V1/3O3
Susumu Okubo, Hideo Wada, Hitoshi Ohta +5
High-frequency ESR results on the S=1/2 Heisenberg hexagonal antiferromagnet InCu2/3V1/3O3 are reported. This compound appears to be a rare model substance for the honeycomb lattic…
Enhancement of the irreversibility field by carbon substitution in single crystal MgB
E. Ohmichi, T. Masui, S. Lee +2
We report the detailed study of the irreversibility field {\hirr} of single crystals of Mg(BC) (=0, 2, 3.5, 5 and 7%) in strong magnetic fields of up to 40 T.…
