| Abstract | We have developed a high-sensitive micro-torsional oscillators and fabricated with a standard silicon process, as a platform to study the low temperatures magnetic properties of micron sized samples. When the oscillator-sample system interacts with a magnetic field, the displacement of the oscillator from its equilibrium position can be detected as a small change in the capacitance (≈ 0.001 pF). We use this device to study the magnetic response of a thick twinned YBa 2 Cu 3 O 7− δ disk when the magnetic field is tilted away from the c axis in the temperature range 80 K < T < 100 K (T c ≈ 92K). | ||||
