“…Sr doped lanthanum manganites (La1-xSrxMnO3) have drawn much attention due to metal-insulator transition and ferromagnetic-paramagnetic transition [1][2][3][4][5][6][7][8][9][10], and it has been found in recent years that infrared emissivity of La1-xSrxMnO3 changes significantly with temperature, as doping level x is near 0.2 [11][12][13][14][15]. K. Shimazaki et al [11] investigated the total hemispherical emittance εH of La1-xSrxMnO3 and found that εH in the vicinity of x=0.2 showed unexpected variation with temperature.…”

La0.8Sr0.2MnO3 was prepared to investigate the infrared emissivity of the sample under 0.76-2.5 μm and 2.5-500 μm infrared fields. The sample exhibited characteristic peaks of rhombohedral perovskite structure at 298-318 K, and split of the main peak weakened with increasing temperature. Intensity of the ferromagnetic resonance peak enhanced with increasing temperature, and the peak was shifted toward high magnetic field. A weak paramagnetic resonance peak appeared at 318 K, indicating that ferromagnetic-paramagnetic transition was occurring. The temperature of the sample under 2.5-500 μm field was higher than that under 0.76-2.5 μm. The emissivity of the sample increased with radiation time under 2.5-500 μm, but it had no obvious changes at about 0.665 under 0.76-2.5 μm. The emissivities at the same temperature fields were higher than those under 0.76-2.5 μm and 2.5-500 μm fields, respectively. It suggested that 0.76-2.5 μm and 2.5-500 μm radiations had inhibition effect on emissivity of La0.8Sr0.2MnO3.

“…The electron beam irradiation (EBI) (also known as electron beam welding) has been widely used in industry, such as rapid thermal processing and surface modification . Since the EBI can control the oxygen concentration and the valence state of elements, it have also been applied for various oxides, like bulk LaMnO 3 , CoO films, and Co‐doped ZnO . In particular, many researches have used the EBI to control the oxygen concentration and the valence state of Mn in the perovskite manganites.…”

“…In this way, the sample size is large enough to characterize its structural and magnetoelectric properties even after EBI. The physical properties of oxygen‐rich LaMnO 3.15 pallet have been modulated after electron been irradiation . The change in Mn–O bond length and the appearance of local distortion caused by EBI play a crucial role in the changing physical properties.…”

Phase separation in the perovskite manganites of R1‐xAxMnO3 (R = trivalent lanthanide cation and A = divalent alkaline‐earth cation) can induce novel phenomena associated with the interfacial interactions. Here, the occurrence of phase separation and unexpected exchange bias induced by electron beam irradiation (EBI) in the epitaxial LaMnO3+δ (LMO) thin films is reported. The transformation from Mn4+ ion to Mn3+ ion originating from the electron's reducibility, enhances the Mn3+–Mn3+ antiferromagnetic superexchange interaction, resulting in phase separation, namely, the coexistence of ferromagnetic matrix and antiferromagnetic clusters. The formation of the antiferromagnetic phase in the LMO film is closely related to the increase of the out‐of‐plane lattice constant and the decrease of Curie temperature after EBI. The unexpected exchange bias effect results from the interfacial interaction between the ferromagnetic matrix and antiferromagnetic clusters, triggered by EBI in LMO film. The discovery of exchange bias induced by EBI shed promising light on achieving the tunable exchange bias effect in spintronic devices for single‐phase films.
