   At temperaturesTmuch lower than its superconducting critical temperatureT_c= 2.1 K, the heavy fermion superconductor UTe₂has a unique phase diagram of magnetic fieldHvs. φ and θ, anglesHis tilted from theb-axis toward thea- andc-axes, respectively, of its orthorhombic unit cell. The phase diagram contains three distinct superconducting phases: SC₁in which φ and θ extend from 0 to 90° andH≤ ~15 T; SC₂for φ ≤ ~7°, θ ≤ ~4° and ~15 T ≤H≤H_m= ~35 T, the onset of the magnetic field polarized (FP) phase, and SC_FPwhich resides entirely within the FP phase in a pocket of superconductivity extending from θ ≈ 20° to 40° and from ~40 T to above 60 T. We studied the evolution of theHvs. θ phase diagram for Th concentrations 0.005 ≤x≤ 0.047 in the U_1-xTh_xTe₂system at ~0.6 K. Within this range ofxvalues, SC₁extends over 0 ≤ θ ≤ 90° andH≤ ~10 T forx= 0.047, while SC₂is suppressed. The SC_FPand FP phases are unaffected tox= 0.02 but are completely suppressed in the regionx= 0.025 to 0.047 where the residual resistance ratioRRR~3 indicates a significant amount of disorder. These results complement recent studies of nonsuperconducting disordered UTe₂single crystals in which the SC₁and SC₂phases are absent, but the FP and so-called “orphan” SC_FPphases are retained.

4. Magnetic moments and spin structure in single-phase B20 Co _1+x Si _1−x (x = 0.043)

   Neutron powder diffraction (NPD) and x-ray magnetic circular dichroism (XMCD) spectroscopy are employed to investigate the magnetism and spin structure in single-phase B20 Co 1.043 Si 0.957 . The magnetic contributions to the NPD data measured in zero fields are consistent with the helical order among the allowed spin structures derived from group theory. The magnitude of the magnetic moment is (0.3 ± 0.1) μ B /Co according to NPD, while the surface magnetization probed by XMCD at 3 kOe is (0.18–0.31) μ B /Co. Both values are substantially larger than the bulk magnetization of 0.11 μ B /Co determined from magnetometry at 70 kOe and 2 K. These experimental data indicate the formation of a helical spin phase and the associated conical states in high magnetic fields.
