Colossal Negative Magnetoresistance Effect in A La${}_{1.37}$Sr${}_{1.63}$Mn${}_2$O${}_7$ Single Crystal Grown by Laser-Diode-Heated Floating-Zone Technique

Si Wu, Yinghao Zhu, Junchao Xia +3

We have grown La${}_{1.37}$Sr${}_{1.63}$Mn${}_2$O${}_7$ single crystals with a laser-diode-heated floating-zone furnace and studied the crystallinity, structure, and magnetoresistance (MR)…
