  text: 'Torque magnetization measurements on YBa2Cu3Oy (YBCO) at doping y=6.67 (p=0.12),
    in dc fields (B) up to 33 T and temperatures down to 4.5 K, show that weak diamagnetism
    persists above the extrapolated irreversibility field Hirr(T=0)≈24 T. The differential
    susceptibility dM/dB, however, is more rapidly suppressed for B≳16 T than expected
    from the properties of the low field superconducting state, and saturates at a
    low value for fields B≳24 T. In addition, torque measurements on a p=0.11 YBCO
    crystal in pulsed field up to 65 T and temperatures down to 8 K show similar behavior,
    with no additional features at higher fields. We offer two candidate scenarios
    to explain these observations: (a) superconductivity survives but is heavily suppressed
    at high field by competition with charge-density-wave (CDW) order; (b) static
    superconductivity disappears near 24 T and is followed by a region of fluctuating
    superconductivity, which causes dM/dB to saturate at high field. The diamagnetic
    signal observed above 50 T for the p=0.11 crystal at 40 K and below may be caused
    by changes in the normal state susceptibility rather than bulk or fluctuating
    superconductivity. There will be orbital (Landau) diamagnetism from electron pockets
    and possibly a reduction in spin susceptibility caused by the stronger three-dimensional
    ordered CDW.'

  text: We report resonant ultrasound spectroscopy (RUS), dilatometry/magnetostriction,
    magnetotransport, magnetization, specific-heat, and 119Sn Mössbauer spectroscopy
    measurements on SnTe and Sn0.995Cr0.005Te. Hall measurements at T=77 K indicate
    that our Bridgman-grown single crystals have a p-type carrier concentration of
    3.4×1019 cm−3 and that our Cr-doped crystals have an n-type concentration of 5.8×1022 cm−3.
    Although our SnTe crystals are diamagnetic over the temperature range 2≤T≤1100 K,
    the Cr-doped crystals are room-temperature ferromagnets with a Curie temperature
    of 294 K. For each sample type, three-terminal capacitive dilatometry measurements
    detect a subtle 0.5 μm distortion at Tc≈85 K. Whereas our RUS measurements on
    SnTe show elastic hardening near the structural transition, pointing to co-elastic
    behavior, similar measurements on Sn0.995Cr0.005Te show a pronounced softening,
    pointing to ferroelastic behavior. Effective Debye temperature, θD, values of
    SnTe obtained from 119Sn Mössbauer studies show a hardening of phonons in the
    range 60–115 K (θD=162 K) as compared with the 100–300 K range (θD=150 K). In
    addition, a precursor softening extending over approximately 100 K anticipates
    this collapse at the critical temperature and quantitative analysis over three
    decades of its reduced modulus finds ΔC44/C44=A|(T−T0)/T0|−κ with κ=0.50±0.02,
    a value indicating a three-dimensional softening of phonon branches at a temperature
    T0∼75 K, considerably below Tc. We suggest that the differences in these two types
    of elastic behaviors lie in the absence of elastic domain-wall motion in the one
    case and their nucleation in the other.
