Growth of α-Fe₂O₃ within nanochannels of Na-4 mica layered structure

Generation of large compressive stress on the α-Fe₂O₃ nanfilms due to mismatch of thermal expansion coefficients of α-Fe₂O₃ and Na-4 mica

Observation of Piezomagnetic effect in α-Fe₂O₃ by changing the measurement temperature

The average values of Piezomagnetic constants extracted are in the range 2.3×$\times$10⁻⁶ to 3.4×$\times$10⁻⁴$\frac{\mathrm{emu}/\mathrm{g}}{\mathrm{kg}/{\mathrm{cm}}^2}$
