Magnetic phase transition in the itinerant helimagnet MnSi: Thermodynamic and transport properties
A careful study of thermodynamic and transport properties of a high-quality single crystal of MnSi at ambient pressure suggests that its transition to a helical magnetic state near 29 K is weakly first order. The heat capacity, temperature derivative of resistivity, thermal expansion, and magnetic susceptibility exhibit a specific structure around the phase transition point, interpreted as a co...
متن کاملUltrasonic studies of the magnetic phase transition in MnSi.
Measurements of the sound velocities in a single crystal of MnSi were performed in the temperature range 4-150 K. Elastic constants, controlling propagation of longitudinal waves, reveal significant softening at a temperature of about 29.6 K and small discontinuities at ∼28.8 K, which corresponds to the magnetic phase transition in MnSi. In contrast, the shear elastic moduli do not show any sof...
متن کاملSurface 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...
متن کاملMagnetic 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...
متن کاملMagnetic 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...
