文摘
- •
Rutile-type β-MnO2 and hollandite-type α-KxMnO2 (x = 0.15 and 0.18) nanorods are prepared by hydrothermal method.
- •
The structural and microstructural properties were studied by SEM and XRD measurements.
- •
Magnetic ordering of β-MnO2 is antiferromagnetic below 93 K.
- •
α-KxMnO2 samples possess complicated low-temperature behaviour of the reentrant spin-glass type.
