(a) Magnetic hysteresis loops of polycrystalline 1 measured at 1.8, 2, 3, 5 and 10 K with a field sweep rate of 500 Oe/s. Solid line is guide for eyes; (b) Hysteresis loops at 1.8 K on the oriented long crystal bundle of 1 along (black) and perpendicular (red) to the ...
Chirping can be used to sweep the wavelength at an extremely high Sensors 2017, 17, 483 13 of 15 speed. This kind of ultrahigh-speed imaging technologies is sometimes called hyperspectral methods. The authors call them time-spectrum conversion methods. The most advanced one of such methods ...
