The Ising-Sherrington-Kirpatrick model in a magnetic field at high temperature [PDF]

, 2004
We study a spin system on a large box with both Ising interaction and Sherrington-Kirpatrick couplings, in the presence of an external field. Our results are: (i) existence of the pressure in the limit of an infinite box.

A coupled model of temperature and pressure based on hydration kinetics during well cementing in deep water

Petroleum Exploration and Development, 2020
Considering the complicated interactions between temperature, pressure and hydration reaction of cement, a coupled model of temperature and pressure based on hydration kinetics during deep-water well cementing was established. The differential method was

Effect of simultaneous application of field and pressure on magnetic transitions in La${_{0.5}}$Ca${_{0.5}}$MnO${_{3}}$

, 2010
We study combined effect of hydrostatic pressure and magnetic field on the magnetization of La${_{0.5}}$Ca${_{0.5}}$MnO${_{3}}$. We do not observe any significant effect of pressure on the paramagnetic to ferromagnetic transition.

Ehrenfest relations and magnetoelastic effects in field-induced ordered phases

, 2005
Magnetoelastic properties in field-induced magnetic ordered phases are studied theoretically based on a Ginzburg-Landau theory. A critical field for the field-induced ordered phase is obtained as a function of temperature and pressure, which determine ...
