Non-Fermi Liquid Behavior in a Weak Itinerant Ferromagnet MnSi
نویسندگان
چکیده
MnSi is a weak itinerant helimagnet with a relatively low order magnetic moment. Temperature dependance of resistivity shows that it enters non-Fermi liquid state above a critical pressure pc which remains to be understood. The observed partial magnetic order above pc indicates novel metallic state. Here, Fermi liquid and non-Fermi liquid theories are discussed with the main focus on the temperature dependance of resistivity. Experimental evidence for the non-Fermi liquid behavior of MnSi has been presented and the partial magnetic order has been discussed.

Quantum phase transitions of magnetic rotons.
Because of weak spin-orbit coupling and broken inversion symmetry the paramagnons of an itinerant, almost ferromagnetic system become magnetic rotons. Using self-consistent Hartree and renormalization group calculations, we study weak fluctuation-driven first-order quantum phase transitions, a quantum tricritical point controlled by anisotropy, and non-Fermi liquid behavior associated with the ...
متن کاملElectrical resistivity across the tricriticality in itinerant ferromagnet
We investigate the discontinuous ferromagnetic phase diagram near tricritical point in UCo1xRuxAl compounds by electrical resistivity measurements. Separation of phases in UCo0.995Ru0.005Al at ambient pressure and in UCo0.990Ru0.010Al at pressure of 0.2 GPa and disappearance of ferromagnetism at 0.4 GPa is confirmed. The exponent of temperature dependence of electrical resistivity implies chang...
متن کاملElectron localization into spin-polaron state in MnSi
Strong electron localization into a bound state has been found in both paramagnetic and ferromagnetic states of the transition metal compound MnSi by muon spin-rotation spectroscopy in magnetic fields up to 7 T and from 2 K to room temperature. This bound state, with a characteristic radius R≈0.4 nm and net spin S=24±2, is consistent with confinement of the electron’s wave function within rough...

J. W. Reiner, L. Klein, A. Kapitulnik, T. H. Geballe, and M. R. Beasley Edward L. Ginzton Laboratories, Stanford University, Stanford, California 94305 (Received 13 March 1998) The reflectivity of the itinerant ferromagnet SrRuO3 has been measured between 50 and 25 000 cm21 at temperatures ranging from 40 to 300 K, and used to obtain conductivity, scattering rate, and effective mass as a functi...
متن کاملProbing the extended non-Fermi liquid regimes of MnSi and Fe
Recent studies show that the non-Fermi liquid (NFL) behavior of MnSi and Fe spans over an unexpectedly broad pressure range, between the critical pressure pc and around 2pc. In order to determine the extension of their NFL regions, we analyze the evolution of the resistivity ρ(T ) ∼ A(p)T at higher pressures. We find that in MnSi the n = 3/2 exponent holds below 4.8GPa ≈ 3pc, but it increases a...
