We theoretically investigate the role of surface Andreev bound states (SABSs)on the phase diagram and spin susceptibilities of superfluid 3He confined to arestricted geometry. We first explicitly derive the dispersion of the SABS in3He-B in the presence of a magnetic field, where the Majorana Ising spin andthe spin susceptibility contributed from the SABS are associated with the SO(3)order parameter manifold. Subsequently, based on the quasiclassical Eilenbergertheory with Fermi liquid corrections, we discuss the nonlinear effect of amagnetic field on the SABS, where the magnetic field is perpendicular to thespecular surface. It is directly demonstrated that a gapped SABS stronglyenhances the magnetization density and spin susceptibility at the surface,compared with that in the normal 3He. To capture the characteristics of theSABS, we show the field- and temperature-dependences of the spatially averagedsusceptibility which is detectable through NMR experiments. It turns out thatthe contribution of the SABS leads to nonmonotonic temperature-dependence ofthe spin susceptibility. Furthermore, we present the superfluid phase diagram,where the B-phase undergoes a first-order (second-order) phase transition toA-phase or planar phase at low (high) temperatures.
