Fig. 4: De Haas-van Alphen effect in Pd3In7.
a Magnetic torque τ at T = 0.35 K and as a function of μ0H for the angle \({\theta }^{{\prime} }={0}^{\circ }\), where \({\theta }^{{\prime} }\) is the angle between μ0H and the (0, − 1, 1) direction. Red line is a polynomial fit to the background. b Superimposed de Haas van Alphen (dHvA) signal, as extracted from the magnetic torque in panel a as a function of inverse magnetic field \({({\mu }_{0}H)}^{-1}\). c, d Fast Fourier Transform (FFT) of the dHvA signal in (b), showing peaks at low and high frequencies that correspond to different extremal cross-sectional areas of the Fermi surface labeled with Greek letters. Peaks labeled by gray colored letters are likely harmonics of the fundamental frequencies, or their combination.
