“…This feature is visible up to 1T due to competition of charge-ordered AFM phase with the long range ferromagnetic order (hence termed T CO ). However, at the higher applied field, i.e., 3T, this minor peak (T CO ) is faded away which is argued to manifest FM domains correlation around this temperature range with an increase in overall magnetic moment of the material [26].…”

“…6 We did not observe any appreciable change in the lattice parameters with increasing Fe concentration. The electrical resistivity was measured by using the standard four-probe technique using an air drying conducting silver paste 20 in the temperature range of 4-300 K. AC susceptibility studies were conducted using a self-made ac probe with a split secondary (astatically wound) and a commercial lock-in amplifier. The ac susceptibilities were measured using the digital signal processing lock-in amplifier (SR830; Stanford Research Systems, Sunnyvale, CA).…”

We have studied the dynamic response of Fe-doped manganites with ac susceptibility measurements in La 0.65 Ca 0.35 Mn 1Àx Fe x O 3 with 0.01 # x # 0.10 as functions of temperature and dc magnetic field. It is observed that the in-phase part of susceptibility goes through a maximum that is removed on the application of moderate dc field. DC fields suppress both the components (real and imaginary parts) with the strongest effects being at or close to T C . Conduction and ferromagnetism have been consistently suppressed by Fe substitution. Increased spin disorder and decrease in T C with increasing Fe content are evident. The effect of Fe is seen to be consistent with the disruption of the Mn-Mn exchange possibly due to the formation of magnetic clusters. There is clear correlation between the resistivity and susceptibility. Low-temperature dissipation in high-Fe-doped samples is observed; that is, increasing the Fe leads to increased spin disorder and dissipation at low temperature. The effect of the dc field is discussed in terms of the suppression of spin fluctuations close to T C .
