From: Experimental observation of drumhead surface states in SrAs3
Observation of quantum oscillations of RAs3. (a,b) Temperature dependencies of the electrical resistivity (note double-logarithmic scales) of SrAs3 and CaAs3, respectively, measured in zero magnetic field and magnetic field of 9 T applied perpendicular to electric current. (c,d) Transverse magnetoresistance of SrAs3 and CaAs3 measured at different temperatures. The inset shows the SdH oscillations in the case of SrAs3 (after subtracting the background from the magnetoresistance data) and lack of the oscillations for CaAs3. (e,f) Magnetic field dependence of magnetization of SrAs3 and CaAs3. In case of SrAs3 a pronounced dHvA oscillation can be observed while CaAs3 shows typical behavior for diamagnetic insulators with no sign of quantum oscillations. The insets show the temperature dependence of magnetic susceptibility of SrAs3 and CaAs3, respectively.
