Magnetoresistance in the helical itinerant magnets MnSi and MnCoSi
A. E. Petrova, S. Yu. Gavrilkin, D. Menzel +2
We studied the longitudinal and transverse magnetoresistance of helical magnets, MnSi and MnCoSi, at temperatures between 1.8 and 100~K and in magnetic fields up to 9 T…
Linear and isotropic magnetoresistance of CoFeSi at x=0.2; 0.4; 0.65
A. E. Petrova, S. Yu. Gavrilkin, V. A. Stepanov +3
We studied the magnetoresistance (MR) of well-characterized samples of CoFeSi at x=0.2, 0.4, and 0.65 at temperatures between 1.8 and 100~K and magnetic fields of 9~T.…
Magnetic Phase Diagrams of Antiferromagnet DyB12 with Jahn-Teller Lattice Instability and Electron Phase Separation
A. N. Azarevich, A. V. Bogach, K. M. Krasikov +6
The origin of charge transport and magnetization anisotropy was studied in DyB12, an antiferromagnetic (AF) metal with Neel temperature TN = 16.3 K that exhibits both cooperative J…
Two-gap superconductor ZrB with dynamic stripes and charge density waves: Crystal structure, physical properties and pairing mechanism
A. N. Azarevich, N. B. Bolotina, O. N. Khrykina +9
A review of long-term studies of ZrB and LuB superconductors with very similar conduction bands and phonon spectra, but with radically different (by a factor of 15-20…
Evidence for spin droplets (ferrons) formation in the heavy fermion metal CeB with dynamic charge stripes
A. N. Azarevich, O. N. Khrykina, N. B. Bolotina +13
The presented studies of resistivity (R), thermal conductivity (k) and specific heat (C) at low temperature 1.8-7 K in magnetic field up to 90 kOe made it possible to detect for th…
Magnetoresistance of a bulk sample of FeSi
A. E. Petrova, S. Yu. Gavrilkin, V. A. Stepanov +2
The magnetoresistance, MR of a well-characterized bulk FeSi sample was studied. It is shown that after a chaotic behavior at temperatures below 6 K, the magnetoresistance of FeSi b…
