Dielectric permittivity ({\\epsilon'}) (and d{\\epsilon'}/dT) portrays the charge order and other magnetic transitions observed in the magnetization measurement. Dielectric study has revealed a relaxation corresponding to ordering of polarons ~ 60 K that follows Arrhenius behaviour both in the presence and absence of magnetic field and another relaxation was noticed ~ 30 K only under a critical magnetic field (3.2 T) that shows critical slow down of electronic charges obeying power law.
