Sub-millimeter propagation of antiferromagnetic magnons via magnon-photon coupling
Ryo Kainuma, Keita Matsumoto, Toshimitsu Ito +1
For the realization of magnon-based current-free technologies, referred to as magnonics, all-optical control of magnons is an important technique for both fundamental research and…
Soft X-ray absorption spectroscopy and magnetic circular dichroism under pulsed high magnetic field of Ni-Co-Mn-In metamagnetic shape memory alloy
Rie Y. Umetsu, Hiromasa Yasumura, Yasuo Narumi +4
In this study, X-ray absorption spectroscopy (XAS) experiments for Ni45Co5Mn36.7In13.3 metamagnetic shape memory alloy were performed under high magnetic fields up to 12 T using a…
Fast acquisition of spin-wave dispersion by compressed sensing
Ryo Kainuma, Keita Matsumoto, Takuya Satoh
For the realization of magnonic devices, spin-wave dispersions need to be identified. Recently, the time-resolved pump-probe imaging method combined with the Fourier transform was…
Ordering tendencies and electronic properties in quaternary Heusler derivatives
Pascal Neibecker, Markus E. Gruner, Xiao Xu +4
The phase stabilities and ordering tendencies in the quaternary full-Heusler alloys NiCoMnAl and NiCoMnGa have been investigated by in-situ neutron diffraction, calorimetry and mag…
Phase transitions in Ni2+xMn1-xGa with a high Ni excess
V. V. Khovaylo, V. D. Buchelnikov, R. Kainuma +6
Ferromagnetic shape memory alloys NiMnGa were studied in the range of compositions . Experimental phase diagram, constructed from differential…
Aging-induced complex transformation behavior of martensite in Ni57.5Mn17.5Ga25 shape memory alloy
V. V. Khovailo, R. Kainuma, T. Abe +2
Ni57.5Mn17.5Ga25 shape memory alloy exhibits a complex transformation behavior, appearing after aging. Aging in the austenitic state resulted in an ordinary decrease of the martens…
