  text: "Superconductor insulator transition in transverse magnetic field is studied
    in the highly disordered MoC film with the product of the Fermi momentum and the
    mean free path kF*l close to unity. Surprisingly, the Zeeman paramagnetic effects
    dominate over orbital coupling on both sides of the transition. In superconducting
    state it is evidenced by a high upper critical magnetic field \U0001D435\U0001D4502,
    by its square root dependence on temperature, as well as by the Zeeman splitting
    of the quasiparticle density of states (DOS) measured by scanning tunneling microscopy.
    At \U0001D435\U0001D4502 a logarithmic anomaly in DOS is observed. This anomaly
    is further enhanced in increasing magnetic field, which is explained by the Zeeman
    splitting of the Altshuler-Aronov DOS driving\r\nthe system into a more insulating
    or resistive state. Spin dependent Altshuler-Aronov correction is also needed
    to explain the transport behavior above \U0001D435\U0001D4502."
