This code may help if you want to get child category of every current category

    getCurrentCategory();
    $currentCategoryId= $_category->getId();
    $children = Mage::getModel('catalog/category')->getCategories($currentCategoryId);
    foreach ($children as $category)
    {
          echo $category->getName(); // will return category name 
          echo $category->getRequestPath(); // will return category URL
    }
    ?>
