Surface Magnetic Phase Diagram of Tetragonal Manganites

To gain insights into the fundamental and characteristic features of the surface of doped manganites, we constructed a general magnetic phase diagram of La1−xSrxMnO3 (001) surfaces in the plane spanned by x and the bulk tetragonal distortion c/a, from the first-principles calculations. We found that the surfaces are quite different from the bulk in the sense that both the (La, Sr)O and MnO2 ter...

Magnetic Structure and Phase Diagram of TmB4

Magnetic structure of single crystalline TmB4 has been studied by magnetization, magnetoresistivity, and specific heat measurements. A complex phase diagram with different antiferromagnetic phases was observed below TN1 = 11.7 K. Besides the plateau at half-saturated magnetization (1/2 MS), also plateaus at 1/9, 1/8 and 1/7 of MS were observed as a function of applied magnetic field B ‖ c. From...

Magnetic phase diagram of the Hubbard model.

The competition between commensurate and incommensurate spin-densitywave phases in the infinite-dimensional single-band Hubbard model is examined with quantum Monte Carlo simulation and strong and weak coupling approximations. Quantum fluctuations modify the weak-coupling phase diagram by factors of order unity and produce remarkable agreement with the quantumMonte Carlo data, but strong-coupli...

Overview of the Phase Diagram of Ionic Magnetic Colloidal Dispersions

We study ionic magnetic colloidal dispersions, which are constituted of -Fe2O3 nanoparticles dispersed in water, and stabilized with electrostatic interparticle repulsion. The phase diagram V versus ( : osmotic pressure, V : particle volume, : particle volume fraction) is explored, especially in the range of high and high . The osmotic pressure of the colloidal dispersion is known either by a m...
