Spin current carrying angular momentum enables intriguing phenomena and many fascinating applications. Here the authors demonstrate that thermally driven spin Seebeck current can give rise to the mechanical torque when transmitting through a Y3Fe5O12

Along with the progress of spin science and spintronics research, the flow of electron spins, (i.e. spin current), has attracted interest. New phenomena and electronic states were explained in succession using the concept of spin current. Moreover, a

We report the observation of the Barnett field, rotational Doppler effect, and Berry phase using the rotating nuclear quadrupole resonance (NQR) method. We have developed coil-spinning techniques that enable us to systematically study the effects of

Hydrodynamic motion can generate a flux of electron-spin’s angular momentum via the coupling between fluid rotation and electron spins. Such hydrodynamic generation, called spin hydrodynamic generation (SHDG), has recently attracted attention in a

We demonstrate that the angular momentum compensation temperature $T_A$, at which the net angular momentum in the sample disappears, can be controlled in Ho$_3$Fe$_5$O$_{12}$ by partially substituting Dy for Ho. The $T_A$ can be detected using the Ba

Enhancement of domain-wall mobility detected by NMR at the angular momentum compensation temperature
The angular momentum compensation temperature $T_{\rm A}$ of ferrimagnets has attracted much attention because of high-speed magnetic dynamics near $T_{\rm A}$. We show that NMR can be used to investigate domain wall dynamics near $T_{\rm A}$ in ferr

The gyroscopic g factor, g ′ , of FeCo nanogranules embedded in a matrix of MgF 2 (FeCo-MgF 2 ) was determined by measuring the magnetic-field generation from a rotating sample due to the Barnett effect. The g ′ value of the FeCo-MgF 2 is estimat

We report direct observation of gyromagnetic reversal, which is the sign change of gyromagnetic ratio in a ferrimagnet Ho$_3$Fe$_5$O$_{12}$, by using the Barnett effect measurement technique at low temperatures. The Barnett effect is a phenomenon in
