Spectroscopic constants and anharmonic force field of dithioformic acid and its isomers: a theoretical study.

The potential astronomical interest dithioformic acid (trans-HC(= S)SH) exists five isomers and has received considerable attention of astronomical observation in recent years. The different positions of H atoms of five isomers lead to diverse point groups, dipole moments, and spectroscopic constants. The anharmonic force field and spectroscopic constants of them are calculated using CCSD(T) and B3LYP employing correlation consistent basis sets.

Magnetic phase diagram of CrPSand its exchange interaction in contact with NiFe.

The magnetic phase diagram of the two-dimensional van der Waals magnet CrPSand the exchange bias effect of CrPSin contact with NiFe film have been investigated. Based on the magnetic measurements, we figure out the relatively low spin-flop field and spin-flip field for CrPS, both of the spin transition phenomena are strongly affected by the temperature. The perpendicular exchange bias effect is studied in CrPSsingle-crystal flake covered with 5 nm NiFe.

Spin switching temperature modulated by the magnetic field and spontaneous exchange bias effect in single crystal SmFeO.

The spin switching and exchange bias effect were investigated in the rare earth orthoferrite SmFeO composed of two antiferromagnetically coupled sublattices Sm and Fe with canted ferromagnetic moments and a temperature induced spin switching in single crystal SmFeO was observed. The spin switching temperature was found to be modulated by exerting different magnetic fields below the compensation temperature ([Formula: see text]). This effect could be explained as the changes of energy barrier related to the magnetization direction under different magnetic fields.
