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."
