    Notes: Abstract The time of separation of the umbilical cord was studied in 911 neonates. The mean time of separation was 7.4 days (SD 3.3, range 1–29 days). We sought a possible relationship between the time of cord separation and various factors in the perinatal period. Cord separation was delayed when antibiotics needed to be administered to the neonate because of sepsis, when the infant was born prematurely, delivered by Caesarean section or had a low birth weight. The cord separated slightly earlier in female than in male infants. None of the infannts studied suffered from omphalitis and it would appear that “delayed” separation of the cord is not always necessarily accompanied by severe leucocyte dysfunction.

    Origin of satellite structures of high field epr in Cd1−xMnxTe (1994)
    Springer
    International journal of infrared and millimeter waves 15 (1994), S. 695-722

    Notes: Abstract The electron paramagnetic resonance (EPR) of Mn2+ in Cd1−x Mn x Te was examined at low temperatures and high magnetic fields with the Mn concentration ranging fromx=0.01 tox=0.65. A far infrared laser was used as a radiation source. The structure of the resonance is strongly influenced by electromagnetic propagation effects. By variation of the sample thickness it was clearly shown that the satellite structures besides the main EPR peak, formerly explained as originating from transitions in the Mn2+ pair energy level scheme, are solely due to interference effects.

    Fir magnetospectroscopy on (CuIn)1−xMn2xTe2 (1995)

    Notes: Abstract The paramagnetic resonance of Mn2+ in the diluted magnetic semiconductor (CuIn)1−xMn2xTe2 was observed in a pulsed magnetic field up to 15 T at temperatures ranging from 4.2 K to 45 K. The temperature dependence of the line width of the paramagnetic resonance in (CuIn)1−xMn2xTe2 resembles the behaviour of other diluted magnetic semiconductors. A Dzyaloshinski-Moriya exchange constant of approximately 0.62 K was derived. This value fits well with the values reported for II–VI based diluted magnetic semiconductors [1], if we consider the larger degree hybridization of the 3d electrons with the band electrons in chalcopyrite semiconductors.
