Structural, electronic, and magnetic entropy contributions of the orbital order-disorder transition in LaMnO(3)
(TAYLOR & FRANCIS LTD, 2011)
Measurements of X-ray diffraction, electrical resistivity, and magnetization are reported across the Jahn-Teller phase transition in LaMnO(3). Using a thermodynamic equation, we obtained the pressure derivative of the ...
Field-induced length changes in the spin-liquid candidate κ-(BEDT-TTF) 2Cu 2(CN) 3
(2012-05-01)
Measurements of the coefficient of thermal expansion on the spin-liquid candidate κ-(BEDT-TTF) 2Cu 2(CN) 3 have revealed distinct and strongly anisotropic lattice effects around 6 K - a possible spin liquid instability. ...

Vortex lattice in two-dimensional chiral XY ferromagnets and the inverse Berezinskii-Kosterlitz-Thouless transition
(American Physical Society, 2020-09)
In this Letter we will show that, in the presence of a properly modulated Dzyaloshinskii-Moriya (DM) interaction, a U(1) vortex-antivortex lattice appears at low temperatures for a wide range of the DM interaction. Even ...
Ginzburg-Landau theory for the magnetic and structural transitions in La 1-y (Ca 1-x Sr x ) y MnO 3
(IOP Publishing, 2019-01)
We present a phenomenological theory for the ferromagnetic transition temperature, the magnetic susceptibility at high temperatures, and the structural distortion in the La 1-y (Ca 1-x Sr x ) y MnO 3 system. We construct ...
