Description:

(abstract)

We report measurements of the in-plane and interlayer magnetoresistances of FeSe. The in-
plane magnetoresistance ∆ρab/ρab(0) for B ∥c is positive below Ts and increases with decreasing
temperature, exceeding 2.5 at T = 10 K and B= 14 T. The field-direction dependence indicates that
the in-plane magnetoresistance is basically determined by the c-axis component of the magnetic
field. The interlayer magnetoresistance ∆ρc/ρc(0) is negative below Ts but turns positive below
∼18 K, which is probably due to the contamination by the large in-plane magnetoresistance. The
field-direction dependence of the interlayer magnetoresistance can approximately be described by a standard formula for quasi-two-dimensional electron systems except near B ∥ab. The experimental magnetoresistance near B ∥ab is larger than the formula, which can be attributed to the so-called interlayer coherence peak. The large width of the peak indicates the correspondingly large interlayer transfer energy.
